DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention are described below on the basis of the drawings.

Overview of Automated Operation Vehicle Control Unit 1

An automated operation vehicle control unit 1 is an automated operation controller implementing an automated operation control function as shown in FIG. 1. The automated operation control function includes an abnormal condition handling function that causes a vehicle 4A to operate in order to notify a person 5B at a periphery of the vehicle 4A of an abnormal condition of a passenger, as a part of the automated operation control function. The abnormal condition handling function may be performed either of while the vehicle 4A is traveling or while the vehicle 4A is stopped. When performed while the vehicle 4A is traveling, the abnormal condition handling function can make a passenger of a vehicle 4B traveling at the periphery of the vehicle 4A notice the abnormal condition. The passenger, who has noticed the abnormal condition, can arrange for a hospital, an emergency vehicle including an ambulance and/or perform first-aid after a stop of the vehicle 4A. Also, when performed while the vehicle 4A is stopped, the abnormal condition handling function can make the person 5B including a pedestrian at the periphery of the vehicle 4A notice the abnormal condition. Note that the automated operation vehicle control unit 1 may be employed during both automated operation and manual operation. When the passenger including a driver falls into the abnormal condition during the manual operation, the current operation mode may be switched into the automated operation, followed by a performance of the abnormal condition handling function.

The term “passenger” may include both a single passenger and a plurality of passengers. The passenger may include all persons riding in the vehicle 4A or may be a person 5A sitting on a particular seat such as a driving seat, a front passenger seat, or a rear seat. Additionally, the passenger is not limited to a human, and may be an animal including a pet. The term “an abnormal condition of a passenger” means poor physical condition which requires the aid of others. Clouding of consciousness, lapse of consciousness, seizure, or spasm by a disorder such as myocardial infarction, cerebral infarction, high fever, hypertension, or hypotension is exemplified as “an abnormal condition”.

The term “vehicle 4A” includes an internal-combustion-engine vehicle employing an internal combustion engine, an electric vehicle employing an electric motor, and a hybrid vehicle employing the internal combustion engine and the electric motor. The electric vehicle includes a fuel-cell vehicle employing a fuel cell. Specific examples of the vehicle 4A include a passenger car, a truck, a motorcycle, a bus, a lawnmower, a recreational vehicle, an amusement-park vehicle, agricultural machinery, construction equipment, a tram, a golf cart, a train, a trolley, and the like. It should be noted that the vehicle 4A in this embodiment is not limited to transport apparatuses that travel on the ground, but includes other transport apparatuses such as a boat, which moves on the surface of the water, an airplane or a helicopter, which moves over the sky. The term “a periphery of a vehicle” means an area where the vehicle 4A can be viewed by a human being. The term “a person 5B at a periphery of a vehicle” means, as shown in FIG. 2, may include the passenger of the vehicle 4B traveling at the periphery of the vehicle 4A, and any persons 5B walking, stopping, or sitting, at the periphery of the vehicle 4A.

Specific Example of Automated Operation Vehicle Control Unit 1

As shown in FIG. 1, the automated operation vehicle control unit 1 includes a detection unit 11 that detects the abnormal condition of the passenger of the vehicle 4A, and a notification unit 12 that notifies the pedestrians 5B 4A of the abnormal condition detected when the detection unit 11 detects the abnormal condition of the passenger. According to these functions, when the passenger falls into the abnormal condition, the notification unit 12 makes the pedestrians 5B aware of the abnormal condition of the passenger by the notification unit 12 and a quick rescue can be achieved.

Automated Operation Vehicle Control Unit 1: Detection Unit 11

The detection unit 11 has a determination function. Namely, the detection unit 11 acquires abnormal-element information from a passenger information acquisition unit 21 that detects at least one abnormal element of body temperature, cardiac sound, breath, and behavior. On the basis of the acquired abnormal-element information, the detection unit 11 determines whether the passenger is in an abnormal condition. The passenger information acquisition unit 21 may include an imaging unit provided with an infrared sensor. The passenger information acquisition unit 21 can detect body temperature of the passenger by means of the infrared sensor and detect blood flow and pulse. Another example of the passenger information acquisition unit 21 includes a mechanism including a pressure sensor, a temperature sensor, a microphone respectively set on a seat. By means of these sensors, the mechanism can detect body temperature, cardiac sound, breath, behavior, and voice of the passenger. In a case where a mobile terminal such as a smartphone or a smartwatch carried by the passenger implements a detection function that enables a detection of abnormal element(s) of, for example, body temperature and/or cardiac sound, the detection unit 11 may have a communicationally-detection function that enables, by a communication with the mobile terminal (as an example of the passenger information acquisition unit 21), the detection unit 11 to detect the abnormal element(s). As shown by an imaginary line in FIG. 1, the automated operation vehicle control unit 1 is electrically connected with a reclining actuator 100 of a seat. This automated operation vehicle control unit 1 causes the reclining actuator 100 to adjust the inclination angle of a backrest of the seat (not shown) such that the backrest is tilted rearward after the vehicle 4A has been caused to stop by a stop unit 13. Such a seat, which can be electrically caused to recline, is typically called a power seat and is well-recognized to be installed on high-end car. This power seat, which cooperates with the automated operation vehicle control unit 1, secures the airway of the passenger, being attacked by a certain physical disorder (the passenger is also a driver in case of a semi-automated vehicle). This airway management can prevent the body condition of the passenger from worsening and provide a first-aid effect.

The passenger information acquisition unit 21 is not necessarily installed inside the vehicle. The passenger information acquisition unit 21 may be an imaging unit which is installed on, for example, a traffic light, a utility pole, a road sign, or a wall surface of a building or the like, and is configured to capture a behavior or the body temperature of the passenger of the vehicle 4A from outside the vehicle. In a case where the detection unit 11 detects the abnormal condition of the passenger on the basis of the abnormal element data captured from outside of the vehicle, the detection unit 11 identifies the vehicle 4A the captured passenger is riding and operates the abnormal condition handling function of the automated operation control function by remote control.

Automated Operation Vehicle Control Unit 1: Notification Unit 12

The notification unit 12 may employ a variety of communication media including voice, light, and radio as long as, by these media, the abnormal condition is notified to the pedestrians 5B. For example, as shown in FIG. 3, the notification unit 12 may notify of the abnormal condition of the passenger by causing lights 41, 42 of the vehicle 4A to light in a predetermined manner. In this case, by the lighting manner of the lights 41, 42, the abnormal condition of the passenger can be noticed in darkness. Examples of “lights 41, 42 of the vehicle 4A” may include headlights 41, small lights (side lights), turn-signal lights, fog lights, brake lights, back lights 42, a license plate light, and an interior light. The term “a lighting manner of the lights 41, 42” means that the lights described above light in a different color or with a different switch interval than usual.

The notification unit 12 may be configured to notify the pedestrians 5B of the abnormal condition with a car horn. Additionally, the notification unit 12 may be configured to transmit a rescue-signal, such as an FM radio wave and output rescue-information in the form of voice from the radio installed in the vehicle 4B at the periphery of the vehicle 4A.

In a case where the vehicle 4A includes transmissive displays 341, 342 disposed on a window, the notification unit 12 may employ the transmissive displays 341, 342 as a notification mechanism of the notification unit 12. That is, the automated operation vehicle 4A may include the automated operation vehicle control unit 1 and the transmissive displays 341, 342 and the notification unit 12 may display the rescue-information about the abnormal condition on the transmissive displays 341, 342. According to this configuration, the rescue-information about the abnormal condition is displayed by the transmissive displays 341, 342. By the display of the rescue-information, a person located far away from the vehicle 4A can recognize the condition of the passenger. The rescue-information may include literal information such as “HELP” and an image such as a video or a static image.

As shown in FIG. 1, when the vehicle 4A includes the display 34 configured to display information in a manner that the information can be recognized by the pedestrians 5B 4A, the notification unit 12 may display message information including personal information of the passenger on the display 34. According to this configuration, the identification information, a medical history, and a transfer destination of the passenger can be acquired easily due to the message information including the personal information of the passenger. The term “display 34” includes a car navigation system and a head up display installed in the vehicle, for example, as well as the transmissive displays 341, 342.

The notification unit 12 may display the message information including the personal information of the passenger on the display 34 after a predetermined time period for observation has elapsed since the vehicle 4A is caused to stop. The term “message information including personal information” means, for example, name, contact information, medical history, or the like, as shown in FIG. 3. According to this configuration, when the passenger remains incapable of having a conversation over the predetermined time period for observation after the stop of the vehicle 4A, the identification information, a medical history, and a transfer destination of the passenger can be acquired easily due to the message information including the personal information of the passenger. Also, the display of the personal information of the passenger is waited until the predetermined time period for observation has elapsed. This configuration can prevent easy leak of the personal information. The predetermined time period for observation may be started at the time when the person trying to rescue speaks to the passenger in the abnormal condition or when the abnormal condition of the passenger is detected, as well as when the vehicle 4A is caused to stop.

The notification unit 12 may display the message information including the personal information of the passenger on the display 34 when the conscious level of the passenger is a level at which the passenger is incapable of communication. According to this configuration, the identification information, a medical history, and a transfer destination of the passenger can be acquired easily due to the message information including the personal information of the passenger when the conscious level of the passenger is a level at which the passenger is incapable of communication.

Automated Operation Vehicle Control Unit 1: Conversation Unit 17

It may be determined whether the conscious level of the passenger is a level at which the passenger is incapable of communication, on the basis of the data acquired from the body of the passenger such as blood pressure, blood stream, pulse, body temperature, or breath. Alternatively, it may be determined on the basis of the content of the conversation with the passenger.

Specific determination process based on the content of the conversation will be described as follows. The automated operation vehicle control unit 1 includes a conversation unit 17 that converses with the passenger when the detection unit 11 detects the abnormal condition of the passenger and a conscious level determination unit 18 that determines the conscious level of the passenger on the basis of the content of the conversation by the conversation unit 17. The notification unit 12 may display the message information including the personal information of the passenger on the display 34 when the conscious level determination unit 18 determines that the conscious level of the passenger is a level at which the passenger is incapable of communication. The conversation unit 17 performs a conversation with the passenger by means of a microphone 24 that collects voice of the passenger and a speaker 35 that outputs voice toward the passenger, if these units are installed on the vehicle 4A. The function of the microphone 24 and the speaker 35 may be provided by employing the speaker 35 as the microphone 24. That is, the speaker 35 may be employed for both a voice output function and a voice acquisition function.

Conversation by the conversation unit 17 is not limited to a conversation by means of a microphone and a speaker. For example, conversation may be performed in a manner that the conversation unit 17 displays questionnaires on the display 34 and then the passenger reads the questionnaires and answers by capturing the motion of his/her fingers or hands, head, mouth, eyes, eyelids or the like by the camera unit. For example, a nod motion is acceptable. In a case where the passenger has difficulties in voicing or hearing sound, conversation with the passenger can be achieved.

Automated Operation Vehicle Control Unit 1: Conscious Level Determination Unit 18

The conscious level determination unit 18 determines the conscious level of the passenger on the basis of the number of correct and incorrect answers of the passenger for the plural questions that have been, for example, the conversation unit 17 asked the passenger about name, date of birth, address and the like. The conscious level determination unit 18 may determine the conscious level of several stages such as low, moderate, severe, and the like. According to the conscious level of each stage, the notification unit 12 may change its operation.

Automated Operation Vehicle Control Unit 1: Stop Unit 13

The automated operation vehicle control unit 1 may include a stop unit 13 that causes the vehicle 4A to stop when the detection unit 11 detects the abnormal condition of the passenger while the vehicle 4A is traveling. According to this configuration, the vehicle 4A traveling is caused to stop and a quick rescue for the passenger can be achieved. As shown in FIG. 2, it is preferable for the stop unit 13 to cause the vehicle 4A, which is traveling in the middle of plural lanes or in a lane that is opposite to the sidewalk, to stop close to the sidewalk where pedestrians are walking. In this case, the person 5B at the sidewalk can immediately come close to the passenger. Also, it is preferable that, when the sidewalks do not exist nearby, for example due to a drive-way such as an expressway, the stop unit 13 searches the nearest sidewalk from the drive-way on the basis of a GPS unit that is an example of local-circumstance-acquisition unit 22 and a map information storage 23, travels to the searched sidewalk, and stops close to the sidewalk. The stop unit 13 may cause the vehicle-installed camera to shoot a sidewalk and cause the vehicle 4A to stop, providing that the stop unit 13 determines that there exists the person 5B on the sidewalk. Furthermore, the stop unit 13 may cause the vehicle 4A to stop after the vehicle 4A has come close to the person 5B at the sidewalk.

Also, when a drone 6 is installed on the vehicle 4A, the stop unit 13 causes the drone 6 to take off outward from an opening such as a window or a door of the vehicle 4A at the same time as or right before the stop of the vehicle 4A. Then the drone 6 may be further caused to fly above, behind, front, and side of vehicle 4A. The drone 6 may have a display plate displaying stop information and the rescue-information while flying. By this configuration, the rescue-information can be notified for a broad area in addition to that rear-end collision can be avoided when a following vehicle is not an automated operation vehicle 4B.

The drone 6 with the display plate may fly behind, front, or side of the vehicle 4A and have the display plate displaying the stop information while landing on a road or keeping a flight in a case of a breakdown of the vehicle 4A. In this case, the passenger does not have to get off the vehicle 4A to install a warning triangle, leading to a decrease of the possibility that the passenger is involved in an accident. Alternatively, the drone 6 may have respective units 11-19 constituting the abnormal condition handling function. Furthermore, the drone 6 may monitor an abnormal condition of the passenger and deal with the abnormal condition in cooperation with the automated operation vehicle control unit 1. In this case, the drone 6 may be provided with the abnormal condition handling function. Also, when the passenger, who gets out of the vehicle while carrying drone 6, falls into an abnormal condition, the drone 6 can detects the abnormal condition and notify of the abnormal condition for surroundings while flying.

Automated Operation Vehicle Control Unit 1: Unlock Unit 14

As shown in FIG. 1, the automated operation vehicle control unit 1 may include an unlock unit 14 that causes a power door lock mechanism 31 configured to lock a door of the vehicle 4A automatically to unlock the door after the stop unit 13 causes the vehicle 4A to stop or while the vehicle 4A is stopped. According to this configuration, the door is unlocked after the stop of the vehicle 4A under the condition that the passenger cannot open or close the door. Thus, the pedestrians 5B 4A can open the door without a vehicle key and bring the passenger out of the vehicle.

Automated Operation Vehicle Control Unit 1: Door-Open Unit 15

The automated operation vehicle control unit 1 may include a door-open unit 15 that causes an automatic door 32 of the vehicle 4A to open while the vehicle 4A is stopped or after the stop unit 13 causes the vehicle 4A to stop. According to this configuration, as shown in FIG. 3, the automatic door 32 is caused to open after the stop of the vehicle 4A under the condition that the passenger cannot open or close the automatic door 32. Thus, the pedestrians 5B 4A can bring the passenger out of the vehicle 4A quickly. Also, as the vehicle 4A remains stopped with its door opened, a person located far away from the vehicle 4A can notice the abnormal condition.

Automated Operation Vehicle Control Unit 1: Window-Open Unit 16

The automated operation vehicle control unit 1 may include a window-open unit 16 that causes a power window 45 of the vehicle 4A to open while the vehicle 4A is stopped or after the stop unit 13 causes the vehicle 4A to stop. According to this configuration, as shown in FIG. 2, the power window 45 is caused to open after the stop of the vehicle 4A under the condition that the passenger cannot operate the power window 45. Thus, the pedestrians 5B 4A can speak to the passenger. The window-open unit 16 may cause the power window 45 to repeatedly open and close. In this case a person located far away from the vehicle 4A can notice the abnormal condition due to opening/closing of the power window 45. Also, the window-open unit 16 or the door-open unit 15 may cause a trunk lid 48 to open or windscreen wipers 46, 47 to swing so that a person far away from the vehicle 4A can easily notice the abnormal condition.

Automated Operation Vehicle Control Unit 1: Restart Unit 19

As shown in FIG. 1, automated operation vehicle control unit 1 may include a restart unit 19 that causes the vehicle 4A to travel to the nearest hospital when the passenger is present in the vehicle 4A after a predetermined time period for waiting a rescue has elapsed since the vehicle 4A is caused to stop. That is, the restart unit 19 searches the nearest hospital on the basis of the GPS unit and the map information storage 23. Also, when the vehicle 4A includes local-circumstance-acquisition unit that can acquire local circumstance data such as traffic jam information or information about construction on each road, the restart unit 19 may search a hospital that can be reached in the shortest time on the basis of the local circumstances as the nearest hospital. According to this configuration, the vehicle 4A, which has once stopped, is allowed to transport the passenger to a hospital when the passenger falls into an abnormal condition at an empty area, in particular, without a person 5B that calls an emergency vehicle.

In a case where securing a person trying to rescue is difficult such as that there does not exist a vehicle 4B or pedestrians 5B around the vehicle 4A, the restart unit 19 may cause the vehicle 4A to function as an emergency vehicle. Namely, the restart unit 19 may search the nearest hospital on the basis of the local circumstance information of the GPS unit, the map information storage 23, and the local-circumstance-acquisition unit 22, and then transport the passenger to the hospital. In this case, it is preferable that the notification unit 12 causes the transmissive displays 341, 342 or lights 41, 42 to display or output emergency vehicle information to notify that the vehicle 4A is an emergency vehicle for the periphery of the vehicle 4A.

In a case where an emergency vehicle mode is set in advance, the restart unit 19 may perform the operation described above as an emergency vehicle under the condition that a person trying to rescue is easily secured at the periphery of the vehicle. Also, it is preferable for the notification unit 12 to inform a police agency or a traffic management center when the vehicle 4A travels as an emergency vehicle. It is also preferable that the notification unit 12 registers emergency vehicle information indicating that the vehicle 4A provided with this notification unit 12 is an emergency vehicle on the traffic management website and that each person 5B that is on another vehicle 4B, working at public transportation, working at the hospital that is a transportation destination can monitor the location where the emergency vehicle traveling. In this case, a person in charge at the hospital of the transportation destination, for example, can make an optimized treatment preparation by the expected time of arrival while monitoring the location where the emergency vehicle is traveling and the condition of the passenger.

Automated Operation Vehicle Control Unit 1: Automated Operation Vehicle Control Program

On the basis of the configuration described above, an example of operations of the automated operation vehicle control unit 1 will be described according to flow charts illustrating automated operation vehicle control program. It should be noted that although description will be made to this embodiment in which the automated operation vehicle control program includes an abnormal condition handling routine as a main routine, and an abnormal condition detection routine, a notification routine, and stop routine as sub routines of the abnormal condition handling routine, the invention is not to be limited to this embodiment and processes of units 11-19 of the automated operation vehicle control unit 1 may be operably programmed respectively.

The automated operation vehicle control program may be acquired through the Internet and installed on the automated operation vehicle control unit 1. Alternatively, the automated operation vehicle control program stored in a storage medium such as a CD-ROM or the like may be installed on the automated operation vehicle control unit 1. That is, the automated operation vehicle control program may have the abnormal condition handling function alone or the automated operation control function including the abnormal condition handling function and may be provided from a server through communication or from a storage medium storing the automated operation vehicle control program therein.

When an operation unit (not shown) of the automated operation vehicle control unit 1 performs the abnormal condition handling routine stored in a memory, respective processes including an incapable-drive-detection process (S1), a notification process (S2), and a stop process (S3) are performed repeatedly.

Automated Operation Vehicle Control Unit 1: Abnormal Condition Detection Routine

In the abnormal condition detection routine, the abnormal-element information output from the passenger information acquisition unit 21 is acquired. The presence or absence of the abnormal condition is determined on the basis of at least one element of body temperature, cardiac sound, breath, and behavior that are included in the abnormal-element information (S11). In a case where the passenger is not in the abnormal condition (S12: NO), normal driving is kept (S14) and the abnormal condition detection routine finishes. On the other hand, when the passenger is in the abnormal condition (S12: YES), a conversation process, namely a conversation with the passenger is performed (S13). Then, a conscious-level-determination process in which the conscious level of the passenger is determined on the basis of the content of the conversation is performed. Either of capableness or incapableness of a conversation is determined as the conscious level (S15) and the abnormal condition detection routine finishes.

Automated Operation Vehicle Control Unit 1: Notification Routine

The notification routine is performed when it is determined that the passenger is in the abnormal condition. First, notification of the abnormal condition by lights such as head lights 41, back lights 42 is performed (S21). Next, as shown in FIG. 3, the message information indicating the abnormal condition is displayed on the transmissive displays 341, 342 disposed on a windscreen 44 and a rear window 43 (S22).

Next, it is determined whether the vehicle 4A is stopped (S23). In a case where the vehicle 4A is not stopped (S23: NO), the notification routine finishes. On the other hand, when the vehicle 4A is stopped, whether the determined result in the conscious-level-determination process is the conscious level at which conversation is possible is determined (S24). In a case where the conscious level is the level at which conversation is impossible (S24: NO), the message information including personal information is immediately displayed (S26) and then the notification routine finishes. On the other hand, the conscious level is the level at which conversation is possible (S24: YES), after a predetermined time period for observation elapses (S25), the message information including the personal information is displayed (S26) and the notification routine finishes.

Automated Operation Vehicle Control Unit 1: Stop Routine

The stop routine is performed when it is determined that the passenger is in the abnormal condition. That is, when the passenger is not in the abnormal condition (S31: NO), the stop routine finishes. On the other hand, in a case of the abnormal condition (S31: YES), vehicle 4A-stop process is performed. Specifically, as shown in the FIG. 8, roadway circumstances are acquired (S321). In a case where the roadway circumstances indicate traffic jams (S322: YES), the vehicle 4A is caused to stop in the current lane (S325), and the stop routine finishes. On the other hand, the roadway circumstances do not indicate traffic jams (S322: NO), whether a sidewalk is present at the lateral side of the roadway is determined (S323). In a case where a sidewalk is present (S323: YES), the vehicle 4A is caused to move to the vicinity of the sidewalk and to stop (S324) and the stop routine finishes.

As shown in FIG. 7, the power door lock mechanism 31 is caused to unlock the door (S33), the power window 45 is caused to open (S34), and the automatic door 32 is caused to open (S35). Note that these unlocking and opening may be performed simultaneously or in a different order. Next, whether the rescue is completed is determined (S36). In a case where the rescue is not completed (S36: NO), a next step is suspended until a predetermined time period for waiting rescue elapses (S37: NO). When the predetermined time has elapsed (S37: YES), the nearest hospital is searched (S41).
